Ships That Von the Greatest Naval War © National Geographic Society Kodachrome, U. S. Navy, Ofliial With Rhythmic Boom a Porcupine Battleship Fires Her 40-mm. Antiaircraft Quads An Iowa-class battleship, such as this, carries 18 of these quadruple mounts. Clips of four shells each are fed to the guns by the smooth-working crew. When our big new battle wagons let go at an attacking plane, they seem on fire, so continuous are the flashes from their 132 or more bristling AA guns. They can steam and maneuver with the carriers. Forming a screen around the task force, they provide antiaircraft cover and protect the lightly armored flattops from surface attack.
